OPERATING INSTRUCTIONS
Overview of the Series 300 Weld Head Operation
An understanding of the processes involved in the weld cycle will be helpful in following the programming
instructions for the Weld Head Control. The Weld Head Control, in conjunction with the Power Supply,
executes the sequence of actions shown in figure 3-1 during the weld cycle. The circled numbers refer you
to the step numbers in weld head cycle table 3-1.
When doing manual welding, the two-level Foot Switch FS2L allows you to move the electrode between the
upstop (UPST) position and the search (SRCH) position as often as you need before completing the weld
with setdown (STDN). This way, you can carefully align the materials to be welded during the first
downstroke of the electrode (first level of the foot switch), then commit to the weld with the final
downstroke of the electrode (second level of the foot switch).
